Definitions
- the flux gate disc 13 is provided with an index mark and a scale is printed in percentage increments on the cylindrical outer surface of the permanent magnet 10.
- the adjustment of the braking torque involves very little change in the magnetic state of the working parts so that the torque required to rotate the magnet 10 from a maximum torque setting to a minimum torque setting is minimal.
- the highest adjustment torque required at the minimum braking torque end of the scale is about three ounce-inches.
